## MCP tools (6)

### `sarb_policy_rate` (~91 tokens)

The SARB (South African Reserve Bank) Policy Rate — South Africa's benchmark monetary-policy interest rate, set by the Monetary Policy Committee. Returns the current rate, the date it took effect, the previous rate and when that one took effect, plus recent decision history (TimeseriesCode MMRD002A), computed from several years of daily observations rather than sarb_timeseries's narrow default window.

### `sarb_home_rates` (~85 tokens)

Current headline South African rates shown on the SARB home page: CPI & PPI inflation, SARB Policy Rate, prime lending rate, government bond yields, Sabor/Zaronia money-market rates, and key Rand exchange rates (USD/GBP/EUR). Each item includes its TimeseriesCode for use with the `sarb_timeseries` tool. No arguments.

### `sarb_current_market_rates` (~51 tokens)

Current South African money-market rates: SARB Policy Rate, Sabor, Zaronia. Each item includes a TimeseriesCode usable with the `sarb_timeseries` tool. No arguments.

### `sarb_cpd_rates` (~69 tokens)

Current Corporation for Public Deposits (CPD) interest rates: interest charged and interest earned. Each item includes a TimeseriesCode usable with the `sarb_timeseries` tool. No arguments.

Input parameters:

- `frequency` (string): Ignored; reserved. Always returns current CPD rates.

### `sarb_exchange_rates` (~88 tokens)

Selected South African Rand exchange rates. frequency="daily" (default) returns latest daily rates (Rand per USD, GBP, Euro, etc.). frequency="monthly" returns latest monthly figures including the nominal and real effective exchange rate indices. Each item includes a TimeseriesCode usable with the `sarb_timeseries` tool.

Input parameters:

- `frequency` (string): daily (default) or monthly.

### `sarb_timeseries` (~239 tokens)

Historical observation series for a single SARB indicator, identified by its TimeseriesCode (obtain codes from home_rates, current_market_rates, cpd_rates or exchange_rates). Examples: "MMRD002A" (SARB Policy Rate — or use sarb_policy_rate directly), "MMRD000A" (prime lending rate), "EXCX135D" (Rand per US Dollar), "CPI1000F" (CPI). Optionally bound the range with start_date and end_date (YYYY-MM-DD); omit both for the most recent ~25 points, not the full history. An unknown code and a valid code with no data in range both come back as a named `no_data` error (the SARB itself cannot tell them apart).

Input parameters:

- `code` (string, required): SARB TimeseriesCode, e.g. "MMRD002A", "EXCX135D", "CPI1000F".
- `end_date` (string): Range end, YYYY-MM-DD (optional). Requires start_date.
- `start_date` (string): Range start, YYYY-MM-DD (optional). Requires end_date.

## Common questions

### What is the Sarb Za MCP server?

Sarb Za is an MCP server listed in the public MCP registry as io.github.pipeworx-io/sarb-za. South African Reserve Bank (SARB) Web API MCP. Keyless. This page covers its npm package (@pipeworx/mcp-sarb-za).

### Is the Sarb Za MCP server safe to use?

Sarb Za scores 84 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Sarb Za MCP server expose?

Sarb Za exposes 6 tools: sarb_policy_rate, sarb_home_rates, sarb_current_market_rates, sarb_cpd_rates, sarb_exchange_rates, sarb_timeseries. Their descriptions and schemas cost roughly 623 tokens of context every time the server is loaded.

### Is the Sarb Za MCP server still maintained?

Sarb Za is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Sarb Za MCP server under?

Sarb Za declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Sarb Za MCP server?

VerifyMCP ran 16 checks on Sarb Za, covering Malware scan, Known CVEs, Install scripts, Dependency health and 12 more. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
